描述

Matter at hand: gh-ost's support for multiple charsets.

gh-ost works well out-of-the-box with utf8 and utf8mb4.

However for other character sets it needs to be told, explicitly, how to convert strings. For example, the latin1 character set is supported, and is converted via golang's charmap.Windows1252, see: https://github.com/github/gh-ost/blob/master/go/sql/encoding.go#L20

If anyone is willing to assist in mapping other MySQL charsets to golang Encoders, we're very grateful. Please PR the https://github.com/github/gh-ost/blob/master/go/sql/encoding.go file with additional charsets.

研究方向
Examine the encoding.go file at go/sql/encoding.go to understand how the existing Windows1252 mapping is implemented. Research commonly used MySQL charsets like latin1, cp1251, utf16, etc., and find corresponding Go encoding packages (e.g., golang.org/x/text/encoding). Add mappings for each charset by implementing the Encoder interface. Test with sample data to ensure correct conversion.
